General description

Platelet derived growth factors (PDGFs) are disulfide-linked glycoprotein dimers consisting of two 12.0-13.5kDa polypeptide chains, designated as PDGF-A and PDGF-B chains. There are three naturally occurring PDGFs; PDGF-AA, PDGF-BB and PDGF-AB. Recombinant human PDGF-AA is a 28.5kDa disulfide-linked homodimer of two A chains (250 total amino acids).

Biochem/physiol Actions

The platelet derived growth factors (PDGFs) are stored in platelet a-granules and are released upon platelet activation. They are involved in a number of biological processes, including hyperplasia, chemotaxis, embryonic neuron development, and respiratory tubule epithelial cell development. Two distinct signaling receptors used by PDGFs have been identified and named PDGFR-α and PDGFR-β. PDGFR-α is high-affinity receptor for each of the three PDGF forms. On the other hand, PDGFR-β interacts with only PDGF-BB and PDGF-AB. These proteins are potent mitogens for a variety of cell types including smooth muscle cells, connective tissue cells, bone and cartilage cells, and some blood cells.

Physical form

Lyophilized from 10 mM Acetic Acid.

Reconstitution

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/mL. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
